Startup Scripts

[neutrino15]

This is probably a very basic question, but how would I go about launching a program on system boot? My ubuntu server is headless and does not run X or Gnome at all, so I can not use the GUI that your documentation suggests.
I am very new to linux, but I essentially want the box to do things like launch ddclient daemon, launch rtorrent, launch apache, etc.. without any human intervention.

Thanks for your help!

Nevermind, I found an article via google:

You may prefer (find it easier) to launch one-shot applications at startup by adding them to /etc/rc.local - this script gets parsed every boot following the completion of the runlevel.

Note that many applications will already be configured to run at boot - e.g. Apache and, presumably, ddclient from your list.
